SkillVis: A Visualization Tool for Boxing Skill Assessment

Motion analysis and visualization are crucial in sport science for sport training and performance evaluation. While primitive computational methods have been proposed for simple analysis such as postures and movements, few can evaluate high-level quality of sport players such as their skill levels and strategies. We propose a visualization tool to help visualizing boxers’ motions and assess their skill levels. Our system automatically builds a graph-based representation upon motion capture data and reduces the dimension of the graph onto a 3D space so that it can be easily visualized and understood. In particular, our system allows easy understanding of the boxer’s boxing behaviours, preferred actions, potential strength and weakness. We demonstrate the effectiveness of our system on different boxers’ motions. Our system not only serves as a tool of visualization, it also provides intuitive motion analysis that can be further used beyond sports science.
